RAPID: A Numerical Investigation of Relativistic Jets from Spinning Black Holes and Neutron Stars

相对论喷流通常出现在吸积黑洞系统中。然而，最近在一些中子星系统中也发现了喷流，这意味着相对论喷流只需要一颗致密的相对论恒星，而不一定是黑洞。该项目包括使用广义相对论磁流体力学程序对黑洞和中子星的相对论喷流进行数值模拟，以确定这两种系统的相似和不同之处。纳拉扬教授的研究生最近在这个问题上所做的初步工作已经产生了非常有趣的结果，而且在短时间内出现了一个机会，让该学生继续研究这个问题，然后再到其他地方从事毕业论文后的工作。由最熟悉的人所做的研究具有明显的内在价值，他的论文研究的这种扩展将为这位初级研究员提供一个在进入职业生涯的下一个阶段之前扩展到一个新领域的机会。该奖项是根据快速反应研究(RAPID)计划颁发的。

Relativistic jets are generally found to occur in accreting black hole systems. Recently, however, jets have also been seen in a few neutron star systems, implying that a relativistic jet needs only a compact relativistic star, and not necessarily a black hole. This project consists of numerical simulations of relativistic jets from black holes and neutron stars using a general relativistic magnetohydrodynamics code, in order to identify similarities and differences in the two kinds of system. Very recent preliminary work on this problem by Professor Narayan's finishing graduate student has led to very interesting results, and an opportunity has arisen at short notice to keep that student working on this problem before taking up his post-thesis appointment elsewhere. There is clear intrinsic value to the research being done by the person most familiar with it, and this extension of his thesis research will provide this junior researcher with an opportunity to expand into a new area before moving on to the next stage of his career.This award is made under the Grants for Rapid Response Research (RAPID) program.
